Portable, collapsible wind screen

Abstract

A portable wind screen is presented where the wind screen is composed of a collapsible metal frame with extendable legs and a fabric or plastic screen connected to said frame with Velcro® fasteners. The frame is fully collapsible and easily stored ion a bag or small box.

What is claimed is: 
     
       1. A collapsible wind screen, the wind screen comprised of a collapsible frame and a screen,
 the collapsible frame comprised of a plurality of tubular metal components connected with hinges and held in place with a plurality of retractible pin fasteners, 
 said tubular metal components comprised of a left extendable segment and a right extendable segment, the two extendable segments placed vertically, each extendable segment comprised of an outer segment and an inner segment, said inner segment fitting slideably inside the length of the outer segment, the inner segment held in place when pulled out of the outer segment by a retractible pin fastener, the two extendable segments connected to each other at the top by a top horizontal segment and at the bottom by a bottom horizontal segment, 
 the top horizontal segment comprised of a left and right top segment, the left top segment connected to the left extendable segment by means of an offset hinge, the right top segment connected to the right extendable segment by means of an offset hinge, the left and right top segments connected rotatably to each other at the middle of the top horizontal segment by means of a hinge and a retractible pin fastener, 
 the bottom horizontal segment comprised of a left and right bottom segment, the left bottom segment connected rotatably to the left extendable segment by means of an offset hinge, the right bottom segment connected rotatably to the right extendable segment by means of an offset hinge, the left and right bottom segments connected rotatably to each other at the middle of the bottom horizontal segment by means of a hinge and a retractible pin fastener, 
 wherein when the frame is in an extended configuration the wind screen defines a plane; and when the frame is moved to a collapsed configuration, the right top segment and the right bottom segment are folded toward the right extendable segment substantially along the plane; and the left top segment and the left bottom segment are folded toward the left extendable segment substantially along the plane; 
 the tubular metal components further comprised of a left short leg, a left long leg, a right short leg, and a right long leg, 
 the left short leg connected rotatably to the bottom end of the left extendable segment at a right angle to the bottom horizontal segment by means of a hinge and held in an extended position by means of a retractible pin fastener, the left long leg connected to the bottom end of the left extendable segment at the other right angle to the bottom horizontal segment by means of a hinge and held in an extended position by means of a vertical bracing member, 
 the right short leg connected rotatably to the bottom end of the right extendable segment at a right angle to the bottom horizontal segment by means of a hinge and held in an extended position by means of a retractible pin fastener, the right long leg connected rotatably to the bottom end of the right extendable segment at the other right angle to the bottom horizontal segment by means of a hinge and held in an extended position by means of a vertical bracing member, 
 the left long leg and the right long leg each connected fixedly to the bottom horizontal segment by means of a horizontal bracing member, 
 the collapsible frame capable of standing upright on the plurality of short and long legs when they are fully extended and braced, the collapsible frame extendable by means of pulling out and adjusting the left and right extendable segments and securing them by means of the retractible pins as well as unfolding the top and bottom horizontal segments and fixing them in place by means of their retractible pin fasteners, 
 the fully extended frame connected to the screen by means of hook and loop fasteners attached to the top and bottom horizontal segments and the left and right extendable segments. 
 
     
     
       2. The collapsible wind screen of  claim 1 , where the screen is comprised of a material selected from the list of fabric or plastic. 
     
     
       3. The collapsible wind screen of  claim 1  where the tubular metal components are comprised of tubular steel with a rectangular cross section.
